The sign "Highways" in Germany indicates that you are approaching a highway or an autobahn. When you see this sign, it means that you are entering a section of roadway where higher speed limits generally apply, and the traffic is expected to move more quickly than on regular roads.

Here are some key points regarding highways in Germany:

1. Speed Limits: While there are areas on the autobahn where there is no specific speed limit, it’s important to observe the posted limits, which may vary. In general, if no signs indicate otherwise, the recommended speed limit is 130 km/h (about 81 mph).

2. No Stopping: On the autobahn, stopping is generally not permitted except in emergencies or if directed by signs. There are designated rest areas where you should stop if necessary.

3. Lane Discipline: Always keep to the right unless passing other vehicles. Use the left lane primarily for overtaking.

4. Merging: When entering the highway, ensure you have enough speed to merge safely and check for traffic.
